This is the first of six days of strike action taking place this summer over the issue of driver only trains.

Trade unions claim that having no guard on the train impacts on passenger safety. Scotrail argue otherwise, although that will matter little to those affected by the limited services or forced to board the bus or catch a lift with colleagues.

Avoid travelling at peak times or "use alternative routes where available or work from home if you can"

Keep your ticket - you'll need them if you want a refund

Can you get a refund?

Yes. And no.

"If there are no trains, replacement buses or ticket acceptance on scheduled buses AND you decide not to travel, you will generally be entitled to a full refund, without administration fee, from your ticket retailer."
